Patented Feb. 2; 19125;

To all whom itmagrcmtcem'r Be it known that I, WALT RL. C. NEES, citizen of the United States, residing; at Saugus, county of Essex, State of Massachusetts, have. invented a certain new and useful. Improvement. in Processesof Making Shoe-Forms, of which the. following is a specification, reference being hedvtherein to. the accompanying drawings.

My invention relates to a new and. improved process of producing, hollow display forms for boots and shoes, and relates especially to that class of such forms which arecovered in at the angle 0 ening. I am aware that heretofore so-cell dcovered in forms have been produced. in various Ways but, so far as known to me, the methods of producing them have been unduly expensive and furthermore the forms themselves have not been perfectly shaped about the ankle portion.

The object of my invention is to produce a covered in form out of a single sheet of material by a simple and inexpensive process, so that the form will be accurately shaped to the configuration of the. last.

My invention will. be. fully understood from the following description, when taken in connection with the accompenyingdrawings and the novel features thereof will be clearly pointed out-and defined in the claims at the close of the specification.

In the draw1ngs -F1gure 1 1s a plan View of a blank from which the form is produced.v

Fig. 2 is a view of the blank shownin Fig. l which has been. folded over and submitted to a crimping operation. Fig. 3 shows the crimped blank died out to the pattern desired, the meeting edges of the heel portion being secured together by stitches. is a side elevation of the blank shaped over a mold or last and having curved side plates which cause the blank to conform to the incurved sides of the mold, that portion of the blank at the ankle extending above the mold. Fig. 5 is e section; on line 55 of Fig. 4. F 6 is a view similar to Fig: 5 showing the projecting edges above theankle drawntightly together over the mold. Fig.

Fig.8 is an elevation of the finished form, themold and the. conr tignous upwardly extending, edges having been removed. Fig. 9, is a section. on line 99 of Fig. 8. Fig l0isa plan viewsof the finished form shown inFigs. 8 and 9.

Having reference to the drawings there is shownin Fig. l a blank A which. consists of leather board or other like sheet materialsuch as isadaptable for'use in the manufacture of hollow-shoe forms. Theblank is blocked out. in the shapeshowm having, a. toe portion B e heel portion C and anankle opening, D.

lhe blank is subjected to a orimpingoperation which is customarily employedto form the instep E of the. form as shown 1n. Fig.

2. In. order-to accomplish this it must be first properly tempered as is well known to those skilled in the artso that it is pliable and readily adapted to be shaped'in the crimping machine. 7 After it is crineped the edges: arecut to the pattern. desired by a die which roughlyconforms the blanks to the required size. Then. the rear edges of the blank are stitched together as. shown at F in Fig. 3. The properly tempered blank is then placed overs. mold G and secured thereto. imthe ordinary manner as by tacks or the like.- The blank is so shaped that otter it has been properly secured to the mold G' theedies H at the ankle opening D extend well a ove the top of the mold, as shown in Figs. sand 5. At the sides of the mold the blank. is secured by curved, side plates 1. These operate to hold the material in close conformityto the in curves of the mold. While theblank is still in. the proper temper the upwardly projecting portions thereof are hentover the topv of the ankle portion of the mold .to form horizontal top covering portions M and contiguousv upturned portions, the turned-up portionbeing drawn tightly together by means of any suitable clamping? device as for instance by clamps P so that the turned edges H come together alongthe median line of the ankle is made to conform more accurately to the top, as is clearly shown in Figs. 6 and 7, and the blank is drawn closely up around the mold. These clamps may be used for performing the bending as well as the drawing up. This drawing up action by the clamps P will pull the blank in a flat plane across the incurved side of the mold unless some means are provided to cause the blank to followthe curve. For'this reason the side plates I'are employed which cause the blank to conform to the curve and retain it in that form while it is being drawn up by the clamps. By this process the sides K of the blank which are held in conformity to the shape of the last by the side plates I are stretched upwardly about the last, and at the same time the ankle covering is formed by the portions M. Thus the whole blank including the ankle covering is all molded to the required shape. The clamps and side plates should be allowed to remain ,until the material has been completely dried out and set, and then the .clamps, side plates and mold are removed. After the blank thus shaped has become dried the upwardly projecting contiguous portions of the edges H may be removed by a suitable knife, being severed flush with the upper surface of the form thusgiving it the finished appearance shown in Figs. 8, 9 and 10. The edges of the flat, horizontal topv portions M come together at L along the median line of the ankle opening and are held firmly together by the sewing F along the heel portion. It will thus be seen that it is not essential to secure the covering members together in any way along the meeting edges.

If it is desired, the portions M,may be covered by a thin piece of sheet material. This may be cemented on' and trimmed 01f at the edges by a suitable knife. Sheet material used for this purpose may of course be very thin and, therefore, easily cut, and it operates as a covering or finish.

By the process above described the form shape of the mold than by any method heretofore employed so far as I am aware, and it is more economical of production.

What I claim is: 1. The process of producing a covered-in hollo'w shoe form out'of a single blank of properly shaped and tempered sheet material, said process consisting of molding and clamping the tempered blank to a mold, in such manner that the top edges of the blank are bent in toward each other over the top of the ankle portion of the mold until they meet together on the top of the ankle portion of the mold, then allowing. the blank to dry while thus shaped and clam ed to the mold, and then removing the mol from the form.

2. The process of producing a covered-in hollow shoe form out of a single blank .of properly shaped and tempered sheet mate rial, said process consisting of shaping and clamping the tempered blank to a mold, in

such manner that'the top edges of the blank .extending contiguous portions forming a fin, then allowing the blank to dry while thus shaped and clamped to the mold, and then removing the mold from the form and trimming off the said fin.

3. The process of producing a covered-in hollow shoe form out of a single blank of properly tempered sheet material having a portion which is to form the covered-in top ankle portion, said process consisting of crimping the blank, placing the crimped blank onto a mold, said covering in portion being so formed that when the crimped blank is placed on the mold the edges of the blank-extend above the top of the ankle portion of the mold, then. drawing up the blank to fit the mold and bending the said upwardly extending portionsof the blank over the top of the ankle portion of the mold until they meet' together and termi-.

nate in upwardly extending contiguous portions forming a fin, then allowing the blank to dry While shaped and clamped to the mold, and then removing the mold from the form and trimming ofl? the said fin.

4. The process of producing a coveredin hollow shoe form out of a single blank of properly tempered sheet material consisting of crimping the blank to form the instep portion, then'placing the crimped and tempered blank on a mold and bending the top edges of the blank over the top of the ankle portion of the-mold, and clamping the form to the mold and allowing it to dry while crimped blank, fastening the blank to the mold by side clamps which conform to the incurved sides of the mold, then drawing up the upper portions of the blank and bending them over the top of the ankle portion of the mold until the two opposite upwardly extending portions of the blank meet together on the top of the ankle portion of the mold, and allowing the blank thus shaped todry while clamped to'the mold.

6. In the process of making hollow shoe forms out of ablank of properly tempered sheetmaterial, fitting the blank over a mold,

applying to the sides of the blank incurved retaining plates which conform to the incurved sides of the mold and securing said I plates and blank to the mold, then bending In testimony whereof I aflix my signathe upwardly extending opposite side porture, in presence of two witnesses.
